In a state where the stop position of the member 27 is held, the locking portion 38 of the second hook 36 is pushed down to get over (see FIG. 11D), and the slide door 3 returns to the fully closed position.

As described above, according to the structure of this embodiment,
The assist grip 11 is rotated and held between the above-described normal position in the substantially upright state and the protruding position in the substantially horizontal state by interlocking with the opening and closing movement of the slide door 3 by the swing operation means 12. Separately, the movement of the assist grip 11 to each of the use positions can be appropriately synchronized with the opening / closing operation of the slide door 3 without secondary rotating operation of the assist grip 11.

Since the swing operation of the assist grip 11 is performed within a predetermined opening movement range after the slide door 3 is opened to a predetermined width, the assist grip 11 swings while the slide door 3 is in a so-called half-door state. Therefore, it is possible to prevent the assist grip 11 of the half-door from protruding to the outside of the vehicle, or to prevent the assist grip 11 from interfering during full closure, thereby ensuring safety and door closeability.

The swing operating means 12 can be easily constituted by a rack and pinion mechanism comprising a rack 18 and a pinion 21, a rack traction mechanism 24, and a stopper 14 for restricting rotation. The upper frame 7 is compactly constructed by a movable piece 27 moving along a rail 25 provided on the upper frame 7 of the vehicle body opening 4 and a wire 28 pulled by the movable piece 27. be able to.

Further, the rack 18 is movably disposed on the rear side opposite to the pinion 21, and is urged by the slider 23 and the spring 22 from the rear side of the rack 18 to always mesh the rack 18 with the pinion 21. Therefore, even if the grip body 11A comes into contact with some obstacle and stops during the swing operation of the assist grip 11, the rack 18 escapes from engagement with the pinion 21 and slides.
